spotlight camera in Iray preview is black

when I change my camera to the spotlight and go to iray preview mode it comes out black.

I've adjusted the luminance, ray length and a host of other settings but it only shows black, changing geometry to sphere, etc.

if I toggle back into texture mode it's fine.

I've tried with scene only and scene and dome but it doesn't seem to change anything

can anyone explain or hazard a guess? thanks.

    It's not buried inside a prop? Texture Shaded doesn't show shadows, so the light would work there but not in Iray. You should also check that the tone mapping is going to allow the light to show.

    Er, is Iray Preview actually supposed to work through a light? (When you try to do an actual render, there is an error message saying you need to select a camera to render through)

     You can look through a Spotlight, I just tried it, I don't know about the others.

    you can camera through a light. you can make a distant light then point to it in the render light source and aim the lights camera on the scene to imitate sunlight which is easier than throwing the dice with date time and longitude; for me anyway.

    RH, it might be buried in a prop I'll try and see with a new light..I also noticed some odd behavior with spotlights not consistantly changing in preview when the lights have changed and had to delete them and past them into newly made copies.

    checking my drivers.
